Application filed llarch7, 1913.? Serial 30.75%859.

To all whom it may concern:

Be it known that 1, CHARLES Wrrnnas BURTON, of'the city of Vancouver, inthe Province of British Columbia, Canada, have invented certain new anduseful Improve ments in Oil-Burners, of which the fol lowing is thespecification.

My invention relates to improvementsin; oil burners. and the object ofthe invention is to devise an oil burner for use in boiler furnaces andthe like, which shall deliver the oil into the furnace immediately afterit has been atomized, and thus obtain the maximum efficiency from theoil and a smokeless combustion in the furnace. I attain this object bythe means illustrated inthe accompanying drawings in which:

Figure 1, is an outside elevation of the burner nozzle. Fig. 2, is alongitudinal section of the burner nozzle on the center line. Fig. 3, isa view looking on the point of the nozzle. Fig. 4, is an outsideelevation of the burner nozzle cap. Fig.1 5, is a longitudinal sectionof the cap on t e center line. Fig. 6, is a longitudinal section of thecomplete burner assembled. Fig, 7, is an outside elevation of the same.

Similar letters refer to similar parts throughout the several views. 7

A is my oil burner.

A? is a nut formed at the back end of the burner.

B is an externally threaded portion ex-' tending from the nut A.

1 G is a reduced smooth tapered portion extending from the'portion B andterminating in a further reduced portion E having an annular groove Dformed therein.

F is an interiorly threaded orificeiormed centrally and extendinglongitudinally it point intermediate the upper wall of the (groove D.

H are orifices exten mg from the orifice G through the portion E intothe groove D.

The holes H provide an outlet from the in- V terior of the nozzle.

J are s iral grooves cut through theouter wall of t e roove D for apurpose which will hereina ter appear.

K is a cap formed with an interior ta pered perip ry L correspondin tothe taper o the tapered portion C of t e'nozzle as shown particularlyFig: 6.

C of the nozzle.

it immediate y passes through the outlet in the cap into the furnace.

.M .is a small orifice extending through the a atom'izing action isfurther increased by providing spirally-cut grooves J in the end of thereduced portion E as shown in Fig. 1. The space M so formed issufficiently large to allow of the roper atomizing of the oil after itleaves t e hole H, that is to say,

when the burner is assembled, the space or distance between the bottomof the recess L and the extreme end of the nozzle is fully equal to thediameter of the outlet hole M.

N is a securing nut provided with an internal thread N which is threadedon to the exterior threaded portion'of the nut A.

O is an annular rabbet groove formed around the cap K and N is anannular flange extending inwardly from the nut N and fitting into therabbet groove 0. By tightening the securing nut N the ca may be drawntight In action, the burner is screwed on, inside the furnace to the. suply' pipe leading oh the main pipe line wli to the burners, this supplyipe being screwed into the screwed recess 1? provided in the burner 'forthis .urpose. The oil feeding throu h the supp y pipe, enters the recessF, as in icated b the arrow points in Fig. 6, passes throug the hole G,and thence throu h the outlets H. It then enters the s iral y cutgrooves J, and "passing through t em, isgiven the spiral or rotarymotion necessary for atomizingit. As soon as it leaves these coves J, inits atomized state It will thus be seen that K up on to the tapere end Ihave devised an 10h feeds the oil oil burner which will deliver theatomized I oil into the furnace immediately after it has been atomized,and in which the atomized oil will have no chance to recover any part ofits density before leaving the' burner, as happens in oil burners wherethe atomizing s ace is too large. Thus, by delivering the 011 into thefurnace immediately after it has been atomized, the eatest efficiency isob tained from it, whi e at the same time the combustion is smokeless.

What I claim as my invention is:

An oil burner comprising a nut having an externally threaded reducedportion a reduced tapered portion and having an annular groove in saidreduced tapered portion and a central orifice extending through the nutto a point-on a line With the exterior wall of the annular groove andhaving peripheral openings extending from the interior of the centralorifice into the groove, spiral Ways extending through the exterior wallof the groove, a cap having a tapered interior periphery fitting theouter end of the tapered exterior periphery of the nut,

and forming an atomizing chamber having an orifice leading therefrom,said cap having an annular rahbet formed thereon, and a securing nutextending around the cap and engaging. therewith and With the thread ofthe nut, said securing nut having an annular flange fitting in saidrabbet as for the purpose specified.
